4 Claims.

This invention relates to improved forceps and is a, division of my co-pending application for patent Serial Number 14,908, filed April 5, 1935, now issued as patent numbered 2,086,317, dated 5 July 6, 1937.

One object of the invention is to provide forceps having jaws so formed as to grasp and hold securely a loop or other object preferably employed for a wire stretching or other operation.

Another object of the invention is to provide forceps having a latch which will permit retention of the forceps in closed position when it is desired to keep them in this position for holding an object tightly clamped between the jaws of the forceps.

A further object of the invention is to provide forceps which will be simple in construction and highly efiicient in operation.

Other objects of the invention will become apparent hereinafter.

My improved forceps are illustrated in the accompanying drawing, wherein:

Figure l is a side elevation view of the forceps.

Figure 2 is a vertical sectional view on the line 22 of Figure 1, looking in the direction of the arrows.

Figure 3 is a fragmentary detail perspective view of one of the jaws of theforceps.

Figure 4 is a fragmentary plan view showing a modified form of latch employed.

Referring now more particularly to the drawing, wherein it will be seen that like numerals of reference designate similar parts throughout the various views, the numeral l indicates in general my improved forceps which comprise companion handle members 2 and 3 pivotally connected near corresponding ends by a pivot pin 4. Relatively wide companion jaws 5 and 6 are formed on the handle members and are located in substantially parallel relation when in closed position. The jaws are provided with opposed substantially U-shaped recesses 1 which open at the free ends of the jaws and extend throughout substantially half the length of said jaws. Each of the recesses is of .a Width equal to substantially half the thickness of its jaw. The recesses are adapted to receive the shanks of bight portions of loops such as described in my co-pending application. It should be understood, of course, that the forceps may be used for any suitable purpose. By reference to Figures 2 and 3 of the drawing, it will be seen that each of the jaws 5 and 6 is of a width equal to substantially four times the width of the handles 2 and 3 at the ill portions thereof where the pivot pin 4 extends therethrough for connecting the arms.

As best seen in Figures 1 and 2 of the drawing, the handle members 2 and 3 are provided with end portions 8 and 9 bent to project in oppositedirections and lie in adjacent arcs so that when the handle members are shifted for clamping an article between the jaws 5 and 6, the portions 8 and 9, or portions thereof, will be disposed in close parallel spaced relation to each other or possibly in sliding engagement with each other throughout their shifting movement. It will be understood that the portions 8 and 9 serve as guides and cooperate with the pin 4 for preventing relative movement of the jaws 5 and 6 during a clamping operation. Moreover, when the jaws 5 and 6 are closed in such a clamping operation, the portions 8 and 9 will define handles affording a sufficient amount of leverage so that turning of the forceps may be readily effected.

Welded or otherwise suitably secured to the bent portion 8 of the handle member 3, near the junction of said bent portion and the main portion of said handle member, is a flat metal U- shaped yoke H] which extends freely about a portion of the bent section 9 of the handle member 2 as well as about a portion of the bent section 8 of the handle member 2. Carried between the arms of the yoke is a latch H which is mounted between the arms of said yoke on a pin l2 and spaced between said arms by means of spacing sleeves l3 and M. The latch comprises a handle 15 and a tapered wedge portion 16 having serrated faces ll thereon. The latch is mounted in such a manner that when the handle I5 is so that said portions will be clamped in the yoke and latch and will be prevented from effecting relative movement. While I have shown the yoke ID as being secured to the portion 8, it should be understood that it may just as readily be secured to the portion 9 without affecting the operation of the latch.

In operation, after an object has been placed between the jaws and the handles moved toward each other for clamping the jaws about the object, the object being carried in the recesses I, the latch handle I5 is shifted for clamping the handle members against relative movement. After this is done the portions 8 and 9 may be engaged for shifting the object clamped between the jaws without danger of slipping of said object from between said jaws.

Referring now to the modification of the invention as shown in Figure 4 of the drawing, the numerals l8 and I9 designate handle members of forceps. The handle member I8 is provided with a series of longitudinally disposed spaced notches 20 which are adapted to be selectively engaged by the bight portion 2| of a loop or ring extending about the members l8 and IS. The loop 22 is elliptical in shape and is shiftable along the members I8 and I9 for locking the jaws of the forceps during operation after they have been engaged about an object. Aside from the foregoing, the modification of the invention operates in a like manner with that of the preferred form.

Having thus described the invention, what I claim is:

1. Forceps including handle members terminating in jaws, means pivotally connecting the jaws, said handle members terminating in end portions projecting towards each other, a yoke carriedby one of said end portions, and a latch carried by the yoke and having a wedge portion adapted to engage between the end portions for locking said handle-members against relative movement.

2. Forceps including pivotally connected jaws andhandle' members terminating in oppositely presented end portions, a yoke carried by one of said end portions, and a latch carried by the yoke between the sides thereof and having a wedge adapted to engage between the end portions for locking said end portions against relative movement, said wedge having a tapered serrated face.

3. Forceps including handle members terminating in end portions disposed in adjacent arcs and extending in opposite directions, means pivotally connecting the handle members, jaws carried by the handle members and adapted to cooperate for clamping an object when the handle members are shifted toward each other, a yoke carried by one of the end portions, and a latch carried by the yoke between the sides thereof and having a wedge portion adapted to be dispo'sed between the end portions of the handle members for locking said handle members against movement with the jaws in clamping position.

4; Forceps including handle members terminating in jaws, means pivotally connecting the jaws and handle members, said handle members terminating inend portions projecting towards each other, a yoke carried by one of said end portions, anclemeans carried by the yoke and operable for engaging between the end portions for locking the handle members against relative movement:
